Specification 0 Application filed August to,

To all whom it may concern Be it known that l, EDWARD Donn, a citizen ofthe United, States, residing at Seattle, in the county of King and Stateof /Vashington, have invented new and useful Closet Attachment, of whichthe following is a specification.

The present invention appertains to a closet attachment, and aims toprovide a novel and improved attachment for Watercloscts, which isadapted to eject or expel the foul gases from the bowl.

The present invention contemplates the provision of a device oi thecharacter indicated, which may be attached to the Water supply pipe ofthe flushing tank, the tlushing pipe leading from the tonic to the bowl,and the discharge or Waste pipe of the bowl, whereby the present deviceor attachment will cliectivel serve its-intendedpurpose, the same havingmeans whereby the gases may be drawn from the bowl by the action of ajet of Water, and whereby the Water and gas will be discharged into theWaste pipe.

it is also Within the scope of the present invention, to provide adevice for Withdrawing and e ecting the foul gases from a bovvl orlatrine, which device will be comparatively simple and inexpensive inconstruction, which may be readily applied to various water-closets, and"which will be practical and eliicient in its use.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the. details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of What is claimed Without departing from the spirit of theinvention.

The invention is illustrated in its preferred embodiment in theaccompanying drawing, vvheyein:

Figure l is a side elevation of the attachment as applied, parts beingshown in section. Fig. 2 is a fragmental side elevation of theattachment looliing from the opposite direction. Fig. 3 is a tragmentalenlar ed front view of the attachment, with the e ector illustrated insection.

lln the drawings, there is designated an ordinary bowl or latrine l,which has its upper portion connected by means of the usual f LettersPatent.

horizontally extending blushing pipe 2 with the bottom of the dusliingtank 3 disposed rear of bowl, the pipe 4i being attached to lower outletof the bowl 1, and an upwardly enten 'ng Water supply pipe 5 beingconnected to the bottom ot the Water tanlr 8 in the usual manner. Thesaid parts are to be merely taken as conven tional, inasmuch as theyvary, and inasmuch as the present device be attached to variousWater-closets.

in carrying out the present invention, a T-coupling 8 is interposed inthe Water sup ply pipe 5, and a forwardly projecting pipe 7 is threadedinto the arm or branch of the coupling 8, projects slightly beyond thefront side of the tanli' An inverted U- shaped pipe 8 has one attachedto the forward end of the pipe branch 7, and is disposed in front oftank 3, the said limb of the pipe 8 a suitable hand controlled valve 9interposed therein for controlling the passage of Water from the supplypipe 5 through the present device. The pipe 8 is preferably supported bymeans of a bracket 10 embracing the crest or upper portion thereof andattached to the front side of the tank 3.

An ejector or siphoning device it is attached to the lower end of theother limb of the pipe 8, and embodies an upright T- coupling or casing12 havin its upper end engaged to the lower end ot the respective limbof the pipe 8, and a nipple or nozzle l3 having its butt end threadedWithin the coupling or casing 12 above its arm or branch it and havingits tip projecting downwardly past the said arm or branch as clearlyseen in Fig. 3. I v

The arm or branch llof the coupling or casing 12 of the ejector hasthreaded thereinto, an eduction pipe in which is in turn threaded orengaged through the top of the flushing pipe 2.

A discharge pipe l6-is threaded or other- Wise engaged into the lowerend of the casing or coupling 12, and has its lower end engaged throughthe top of the Waste pipe 4, the pipe 16 beingpreferabl provided with adouble bend or trap 17 flit prevent ing the foul gases from risingthrough the pipe 16 from the Waste pipe 4, as will be obvious.

The present device is of simple and inexpensive construction, thesamebeing mainly formed of piping, elbows and T-couplings,

Q memos and it will be evident that the present device or ettechrnentmay he reedily applied to the water supply pipe 5, the flushing pipe 2end waste pipe 4. v

5 In operation, when the closet is occupied, the valve 9 may be readilyopened, which will permit the weter'to tlow from the supply pipe 5through the pipe or hrench 'l end the pipe 8 into the ejector oatsiphoning do 10 vice ll. Thus, the water being discharged through thenipple or nozzle 13 downwardly into the discharge pipe 16, will tend tocreate a vacuum within the casing or coupling 12, end as s result thesuction crv 15 eted will extend through the eduction 15 end flushingpipe 2 to the howl or letrine It. llt will he evident that the flushingpipe 2 is ordinarily empty, so that the suction created by the ejectorll would drew.

the foul gases from the bowl or letrine l, and

the gases will he discharged through the pipe 16 into the waste ordischerge pipe The withdrawal of the gases from the bowl will continueas long as the valve 9 is open,

and the present device or attachment will not interfere with thesiphonic action when the bowl 1 is flushed in the usual manner. Thus,when the water is erinitted to flow from the tank 3 through t e flushingpipe 2 into the bowl 1, to start the siphonic action,

the pipe 2 being'filled with water will prevent air being taken inthrough the present device, which would be liable to brook the siphonwithin the trap or siphon of the bowl 1 and the wuste pipe 4. lt ispreteruble to close the valve 9 es soon es the bowl 1 is flushed, tobring the present device out of operation by shutting out the flow ofwater to the present device from the supply 40 pipe 5. It will also benoted that the trap 17 will ordinarily be tilled with water, when i thepresent device is idle, to prevent the gases rising from the waste pipel through the present deviw end into the howl 1.

From the foregoing taken in connection with the drawing, the advantagesand cepehilitieso'f the present device will he obvious to those versedin the ert, it being understood that the present device may he alteredin its details in adopting it to various closets end to veriousenvironments.

Hevini thus described the invention, whet is cleirnee as new is in orwater closet, the combination with e howl, e. west/e pipe for the howl,e flushing tenlr in rear of the bowl, .e horizontelly extending flushingpipe connecting the bottom of the tank end the upper portion of thebowl, and on upwardly extending WitlZGi' supply pipe connected to thebottom of the to tenlx, of e forwardly projecting branch connected tothe supply pipe, en inverted U- sheped pipe disposed in front of thetank end having one lirnlo connected to the front end of the saidbranch, one limb of the said ll-shaped pipe'hsvingg, e vnlve, e bracketettorched to the front of the tent: and having means engaging the crestportion of the U- sheped pipe to support the some, en ejector embodyingan upright T-cesing end e nozzle heving its hutt end secured thereinabove the term thereof and having its tip projecting downwardly pest thesold arm, the upper end of the casing being engaged to the lower end ofthe other limb of the U-shsped pipe, on eduction pipe connected to thearm of the casing and the top of the U sheped pipe, and e ischurge pipeconnected to the lower end of the seid casing and the waste lpe.

p In testimony that l cleim the foregoing as my own, ll hove heretoeffixed rny signature in the presence of two witnesses.
